    I have to admit that, when calculating logarithms, I use my trusty 1993 Radio Shack model EC-4028 10-digit Scientific Calculator. That old calculator is like a Timex watch! It "takes a lickin' and keeps on tickin'!

    I played hockey last night. A member of the opposing team and our captain collided at mid-ice and when they finished pulling themselves up from the ice, there was a bunch of jawing, trash talk and shoving. The gloves came off, sweaters were grabbed, pads littered the ice.

    Then a part 97 rules discussion broke out.

    I would hazard a guess that 30 Meters and 60 Meters have the largest number of hams exceeding the legal limit 200W / 100W ERP.

    What if they held a Part 97 discussion and an NEC discussion broke out? "Oh, the humanity!". ;)

    If you're using a tuner on an 80 meter dipole to get on 60 metrers - you're going to be handicapped compared to the guy running a dipole cut for 60 meters ... maybe this is the source of the differences seen?

    This has been our experience in Texas, the cut-for-band dipole on 60m outperforms the tuner+80m dipole lashup.

    I would be hesitant to ever try my LK-500ZA or SB-220 on 60 meters on account of 1) tuned input match circuit and 2) encountering strange resonances in the PA Plate "choke".

    ^^This^^ Seems to take some folks a long time to "tune" on 30 meters, What are they tuning?
